i had unprotected sex July 13. I've had symptoms like the milky white discharge, lower back pain, my eating habit changed, i sleep for long periods of time, cramping. well 14 days later i have (what i think is my period). i started yesterday July 27th. im kinda bummed bout it. but then i notice that my period is different.the first 2 days of my period its usually really heavy and need to change every hour. and i always had medium blood clots. well with this period i change every 4 hours and still wouldn't need to change. i have a couple tiny blood clots like the top of a pen cap. i was wondering if i could still have a period this month since its only been 2 weeks ago. girls, is it possible i may be pregnant? comments would be great thank you.
